These initial decisions are not a formality. They are an essential part of any well-considered residential design process. In complex and highly valuable contexts such as Jávea, where landscape, climate and planning regulations play a decisive role, understanding the place before designing is a matter of architectural responsibility.

Starting with form: a common mistake

It is very common for a project to begin with references, images or preconceived ideas about volumes and aesthetics. However, when architecture starts from form rather than analysis, conflicts quickly arise with the reality of the plot, local regulations or the actual way the house will be used.

Good architecture does not impose an idea onto a place. It interprets it. And requires pausing before drawing.

The plot is not just a datum – it is the project

A plot is more than a buildable surface. It is a set of conditions that define how a house can — and should — be built.

Orientation, topography, distant and immediate views, access points, neighbouring buildings and shadows all directly influence the layout, volume and organisation of the villa. Ignoring any of these aspects at an early stage usually leads to forced changes later, affecting both architectural quality and cost.

Understanding the plot as an active part of the project is one of the key differences between a standard villa and a truly well-designed one.

Planning regulations: the visible framework

Planning regulations should not be something checked at the end of the process. They define the framework within which the project must operate from the beginning.

Maximum heights, buildability, setbacks, permitted typologies or roof conditions all shape the design, even when they are not immediately visible. When regulations are understood early on, they become part of the design logic rather than a limitation.

This is where proper architectural guidance is essential, allowing the project to develop with clarity and coherence.

Climate and real use: designing beyond the image

Designing a villa is not only about summer living. Winter sun, wind exposure, humidity, natural ventilation and the relationship between indoor and outdoor spaces all affect comfort throughout the year.

Equally important is how the house will actually be used. A permanent home requires different decisions than a seasonal residence. Designing purely for appearance often results in houses that look good but are uncomfortable to live in long-term.

Anticipating real use is a fundamental part of responsible residential architecture.

Budget and expectations: aligning them from the start

Another common mistake is postponing discussions about budget. In reality, the order in which architectural decisions are made has a direct impact on the final cost of the villa.

Clarifying priorities, understanding what truly adds value and avoiding unnecessary complexity leads to a more coherent and efficient project. Well-designed architecture is not about adding more elements, but about making better decisions.

When early decisions are right

When these aspects are properly addressed from the outset, the project evolves naturally. Design decisions make sense, changes during development are minimal, and the final villa responds clearly to its environment, climate and users.

This is why working with an architect in Jávea from the earliest stages makes a real difference. Not only in the final design, but in the entire experience of the process. Because a well-designed villa does not begin with drawings — it begins with the right decisions.

Frequently ASked Questions

Why is it so important to make key decisions before designing a villa?

Because factors such as orientation, planning regulations, intended use and budget shape the project from the very beginning and are difficult to change later on.

When is the right time to work with an architect?

From the earliest stages, even before defining the design concept or purchasing the plot, in order to assess feasibility and avoid fundamental mistakes.

Do planning regulations limit architectural design?

No. When properly understood, planning regulations provide a framework that can be naturally integrated into the design process.

What are the benefits of working with local architects?

Local knowledge of the context, regulations and environment, which is especially important in places like Jávea.

At our architecture studio, we’ve guided many clients through this type of project. And if there’s one thing we’ve learned, it’s that the most costly mistakes are rarely visible—they’re usually technical: damp, condensation, water ingress, material deterioration, or poor insulation. That’s why today we’re sharing a guide to the most frequent issues and practical solutions for building with intelligence, durability, and confidence.

Ambient humidity: The silent enemy

One of the defining features of coastal areas is the high level of relative humidity in the air. In humid climates, such as that of the Costa Blanca, excess moisture can seep into porous materials, damage interior finishes, and encourage the growth of mould.

How can it be avoided?
The key lies in choosing materials with low absorption and good breathability. Installing vapour barriers in roofs and walls, incorporating natural cross ventilation, and using controlled air renewal systems help maintain the home’s hygrothermal balance. In addition, applying waterproof exterior coatings and using ventilated façade systems can make a significant difference.

Interior condensation: When moisture comes from within

Not all excess moisture comes from outside. In a poorly ventilated or inadequately insulated home, steam generated by showers, cooking, and daily activities can condense into droplets on cold surfaces such as windows, walls, and ceilings.

How can it be avoided?
Ensuring proper ventilation—whether natural cross ventilation or mechanical systems—is essential. Effective thermal insulation also prevents the formation of thermal bridges, which are often the source of condensation. Choosing window frames with thermal break and double or triple glazing helps to maintain a stable indoor temperature.

Rainwater or saltwater ingress

Coastal climates bring more than just humidity—they also expose buildings to heavy rain, strong winds, and, in many cases, the corrosive effects of the sea. Without proper waterproofing, water ingress can cause serious structural damage in a short time.

How can it be avoided?
Before building, it’s crucial to study the plot’s topography and how water behaves on the site. From this, roof slopes, drainage systems, concealed gutters, and technical solutions such as waterproof membranes on roofs and terraces can be planned. In addition, using water-repellent mortars on plinths or lower walls can offer effective protection for the most vulnerable areas.

Poor thermal insulation: Comfort and energy efficiency at risk

Many coastal homes are built with the assumption that “extensive insulation isn’t necessary” due to the mild climate. However, this is one of the most common mistakes when building a house by the sea. Inadequate insulation leads to overheating in summer, cold interiors in winter, and a significant increase in energy consumption.

How can it be avoided?
Insulation should never be overlooked, even in warmer regions. Incorporating continuous thermal insulation in façades, roofs, and floors—alongside controlling air infiltration and improving the solar performance of the building envelope—helps maintain a stable indoor temperature without over-reliance on mechanical systems.

Corrosion and material deterioration due to salt exposure

Living close to the sea means greater exposure to salt in the air, which can deteriorate metals, paints, fittings, and finishes. Railings, external joinery, and even electrical systems can suffer damage if unsuitable materials are used.

How can it be avoided?
Choose corrosion-resistant materials such as marine-grade stainless steel (AISI 316), anodised aluminium, or specially treated wood and metal finishes. It’s also important to protect fixings, screws, and anchor systems, and to carry out regular maintenance to extend the lifespan of each element.

Foundation issues due to unstable or damp ground

Coastal soils are often sandy, damp, or unstable—factors that directly influence the choice of foundation type. If miscalculated, this can lead to differential settlement, structural cracks, and displacement.

How can it be avoided?
A preliminary geotechnical study is essential. Only with a full understanding of the ground conditions can the appropriate solution be selected—whether continuous footings, reinforced slabs, piles, or mixed systems. At our architecture studio, we never begin a build without a complete terrain assessment, no matter how appealing the plot may seem.

Extreme sun exposure: Interior comfort and exterior deterioration

In coastal areas, solar radiation is intense for much of the year. This not only impacts interior temperatures but also affects the longevity of exterior finishes, awnings, paints, and roofing.

How can it be avoided?
The design should make the most of natural light while preventing harsh sunlight from directly hitting façades. Eaves, pergolas, louvres, and adjustable shutters can all help regulate sunlight depending on the season. Choosing light-coloured materials and finishes that are resistant to UV radiation also helps preserve the building’s appearance and performance over time.

Building on the coast with care and experience

Building a home by the sea is an investment in quality of life. But to ensure that experience doesn’t turn into a series of repairs, maintenance issues, and unpleasant surprises, it’s essential to plan properly from the outset.

At La Quinta Fachada Arquitectura, we design each coastal home with the environment, climate, and real use of the space in mind. We anticipate common problems with long-lasting construction solutions, suitable materials, and a technical approach grounded in experience.
